20100082825 | INTEGRATING ENTERPRISE IDENTITY AUTHORIZATION IN CONFERENCES - Disclosed herein are embodiments for validating a user joining a conferencing session. According to various embodiments, a first identifier is received. A user is identified from a plurality of users based at least in part on the first identifier. A second identifier is received that corresponds to the first identifier and the user and the user is validated based on both the first identifier and the second identifier. The user may then join the conferencing session, with the user's identity being revealed to others attending the conferencing session. | 04-01-2010 |
20100223334 | DISTRIBUTED ROUTING OF CONFERENCES USING CONFERENCE IDENTIFIER - Users attempting to join a conference facilitated by an enhanced communication system employing a network communication protocol such as SIP and having a distributed architecture are enabled to request the conference through a numeric conference identifier. The conference directory identifier is assigned to an associated resource, rather than directly to a pool of resources in the communication system. If a pool is decommissioned, any conference directories with remaining data may be assigned to other pools, like users may be moved, to ensure continuity of the system. | 09-02-2010 |
20110295957 | CONTINUOUS REPLICATION FOR SESSION INITIATION PROTOCOL BASED COMMUNICATION SYSTEMS - User defined routing rules are managed within a primary/backup architecture through continuous replication between home servers and their corresponding presence servers in an automatic manner. User set-up rules are stored and published by a designated presence server to home servers on which the user can register including the user's home registrar and any backup registrars. Changes to the rules may be disseminated and synchronized through comparison of versions and exchange of batches between the presence server and registrars. | 12-01-2011 |
20110307541 | SERVER LOAD BALANCING AND DRAINING IN ENHANCED COMMUNICATION SYSTEMS - Resilient load balancing servers in an enhanced communication system is provided mitigating server failures or scheduled shutdowns. A repeatable but virtually random sequence of servers is generated for a given pool of homogeneous servers based on a user identifier in a request message. If a request cannot be routed to a first choice server, for any reason, then subsequent servers in the sequence are selected. A communication protocol within the system is adapted to permit an individual server to indicate that it cannot accept new requests. Following the indication from the server, traffic associated with existing dialogs is allowed to continue to be processed by the server, but new dialogs are directed to other servers. | 12-15-2011 |
20120209913 | INTEGRATING ENTERPRISE IDENTITY AUTHORIZATION IN CONFERENCES - Disclosed herein are embodiments for validating a user joining a conferencing session. According to various embodiments, a first identifier is received. A user is identified from a plurality of users based at least in part on the first identifier. A second identifier is received that corresponds to the first identifier and the user and the user is validated based on both the first identifier and the second identifier. The user may then join the conferencing session, with the user's identity being revealed to others attending the conferencing session. | 08-16-2012 |
20120221642 | HIGH AVAILABILITY CONFERENCING - A method, system, and architecture for providing a conference system that effectively achieves high availability conferencing is provided. The conference system architecture provides a conference system that comprises a set of stateless conference servers and a shared conference store to provide highly available conferencing to its users. The conference servers serve (host) conferences (meetings) that allow users to conduct distributed conferences. Each conference server generally performs conference provisioning operations and conference control operations. The shared conference store provides for the storage of conference state information, thus allowing the conference servers in the conference server pool to be stateless by maintaining conference state information on the shared conference store. A stateless conference server may also locally maintain, for example, in cache memory, some of the conference state information that is maintained on the shared conference store. | 08-30-2012 |
20130070912 | UNIVERSAL PHONE NUMBER FOR CONTACTING GROUP MEMBERS - A universal phone number is provided for connecting to communication methods, including fixed line, mobile line, and internet communication methods. A communication group of communication methods may include multiple communication methods belonging to one individual or to multiple individuals within the communication group, such as a family. The universal phone number may be designated as the primary contact number for the communication group such incoming phone calls and text messages may be automatically routed to the communication methods in the communication group. The universal phone number may provide alerts to the multiple communication methods for notifying when incoming phone calls are answered. A universal voicemail box may also be provided for a scenario when the incoming call is not answered. Additionally, the universal phone number may provide the ability to keep the contact information for each of the individual communication methods private. | 03-21-2013 |
20130263216 | PARTICIPANT AUTHENTICATION AND AUTHORIZATION FOR JOINING A PRIVATE CONFERENCE EVENT VIA A CONFERENCE EVENT ENVIRONMENT SYSTEM - Concepts and technologies are described herein for a mechanism by which participants who have been invited to attend a conference event and who are physically present within a conference event environment, such as a meeting room, can provide authentication credentials to join the conference event via a conference event environment system. When an individual attempts to join a conference event via a conference event environment system, the individual is prompted to provide his or her authentication credentials to join the conference event via the conference event environment system to participate in the conference event. The conference event environment system may inherit the individual's permissions, such as in regards to whether or not the individual has been permitted to present content during the conference event. A conference event roster may be used to indicate that the individual has joined the conference via the conference event environment system. | 10-03-2013 |
20140136878 | Scaling Up and Scaling Out of a Server Architecture for Large Scale Real-Time Applications - Scaling up and scaling out of a server architecture for large scale real-time applications is provided. A group of users may be provisioned by assigning them to a server pool and allotting them to a group. Grouped users help to reduce inter-server communication when they are serviced by the same server in the pool. High availability may be provided by choosing a primary server and one or more secondary servers from the pool to ensure that grouped users are serviced by the same server. Operations taken on the primary server are synchronously replicated to secondary servers so that when a primary server fails, a secondary server may be chosen as the primary for the group. Servers for multiple user groups may be load balanced to account for changes in either the number of users or the number of servers in a pool. Multiple pools may be paired for disaster recovery. | 05-15-2014 |
20140137187 | Scalable and Highly Available Clustering for Large Scale Real-Time Applications - Scaling and highly available clustering for large scale real-time applications is provided. A ring may be formed which includes multiple nodes for providing a set of services in a system. When a network partition is detected which affects communications between each of the nodes in the ring, the formation of additional rings is prevented by shutting down nodes which include a minority of voting nodes in the ring while maintaining the availability of the nodes which include a majority of the voting nodes to continue providing the set of services in the system. | 05-15-2014 |
